Meg Ryan joins 'How I Met Your Mother' spin-off

Meg Ryan has been cast as the narrator for the How I Met Your Mother spin-off. The unseen voice-over part is the future version of the sitcom's main character Sally (Greta Gerwig), much like Bob Saget's role in the original.

Ryan, perhaps best known for her many rom-com roles, has never taken a series regular part in a prime-time TV show. Maybe she took this one because she has a chance to play another character named Sally on the path to meet the man of her dreams.
